carbonated may have a pH as low as 3

a)what ions would affect the pH of a human body when carbonated drinks are consumed?

i think that it's due to H+. does anyone knows the answer 

b)when these drinks are consumed, the pH of a human body would remain constant. Give a reason

is it because there are both H+ and OH- found in the carbonated drink and therefore, the pH of a human body remain constant???
